x-labels behave weirdly in semilogx plot.

[Yakonshus]

Hi! Thanks for the tool, I'm not so skilled in python and I need to plot something so devious as a logx plot with the data points presented as x time after stimulation, a zero point. I have three problems

In the plot, the beginning and end of the first xlim is always ticked ( 6 x 10^0 and 2 x 10^1) - How do I remove this?

I want to label the ticks that corresponds to my x values. In the log scale, it only wants to label clean log10 values, and not intermediates such as 500, 1500 etc... The way I do it now, the distance between the major ticks is not the same either. That looks weird in a log plot.

I circumvented the x-value zero by saying that x value of the stimulation time is 10, but in the plot I would like to make a custom tick that says this point is 0, or stimulation time.

x = [10, 500, 1500, 15000, 150000]

fig = plt.figure(figsize=(6,4))
bax = brokenaxes(xlims=((6,20),(300,400000)), wspace=.08, xscale='log')

bax.semilogx(x, wt_master, 'o', ms=8, label='ChR2-wt')
bax.semilogx(x, dc_master, 'x', ms=10, label='ChR2-XXL')

bax.vlines(10,-1,3,color = 'k', linestyles = 'dashed', alpha=0.8)

bax.legend(loc='upper left')
bax.grid(axis='both', which='major', ls='-')
bax.grid(axis='both', which='minor', ls='--', alpha=0.3)
bax.set_ylabel('Normalised Membrane Current')
bax.set_xlabel('\nTime after peak current [ms]')
bax.set_ylim(0,2)

bax.axs[0].set_xticks([0])
bax.axs[1].set_xticks([500,1500,15000,150000])
plt.show()

could you provide the data?

I think you want to work with bax.axs[1].set_xtickslabels

Thanks for the quick reply!

The yellow crosses have the y-values:
dc_master = [1, 0.97191375, 1.1808187, 1.3289762, 1.4749643 ]

If I try set_xtickslabels I get

AttributeError: 'AxesSubplot' object has no attribute 'set_xtickslabels'

Though right now I just moved to plotting it without log scale and just define my own positions with matplotlib so I don't have to break.
